Internal documents from the Boy Scouts of America reveal more than 125 cases in which men suspected of molestation allegedly continued to abuse Scouts, despite a blacklist meant to protect boys from sexual predators.

A Los Angeles Times review (http://lat.ms/OT9zx5) of more than 1,200 files from 1970 to 1991 found suspected abusers regularly remained in the organization after officials were first presented with sexual misconduct allegations.

Predators moved from troop to troop because of clerical errors, computer glitches or the Scouts’ failure to check the blacklist, known as the “perversion files,” the newspaper said.

In at least 50 cases, the Scouts expelled suspected abusers, only to discover they had re-entered the organization and were accused of molesting again.

In other cases, officials failed to document reports of abuse in the first place, letting offenders stay in the program until new allegations came to light, the Times reported.
